48k or 96k frame (only active in SMUX/2 mode - 64-96kHz)
In 48k frame mode, two channels are combined. In this way, the 64 MADI channels are bundled into 32 channels. In 96k frame mode, shorter
frames of 32 channels each are sent directly. Both formats transmit the same number of channels (32), but the 96k frame mode has the
advantage that the receiver can distinguish between SMUX/1 and SMUX/2 operation and switch automatically.
Make absolutely sure that in SMUX/2 mode the frame format is set identically on all devices.
Short frame (56Ch) or full frame (64Ch)
The MADI format in its first version (short frame) had a channel count of 56x56 channels. In addition, the speed of the channels could be shifted
by 12.5% to enable synchronisation with tape machines ("Varispeed"). Later, the MADI format was extended to full frame mode, where Varispeed
was dropped and the freed bandwidth was converted to a higher channel count of 64x64 channels. Make sure that the selection of the format is
identical for all MADI devices.
Latency compensation
In the case of daisy-chaining, a latency of 3 samples occurs at the MADI interface. By choosing the correct position in the chain, this latency is
compensated so that all signals are output coherently again. You can choose between "single device" (only one device), "1 of 2 devices" (first of
two devices) and "2 of 2 devices" (second of two devices).
MADI Input (Priority)
Here you can select the priority of the two MADI SFP ports (1&2) via one of the four presets:
Use SFP1 only
- uses only SFP slot 1
Use SFP2 only
- uses only SFP slot 2
Use SFP1 with priority
- uses SFP slot 1 and switches to SFP slot 2 in the event of an error.
Use SFP2 with priority
- uses SFP slot 2 and switches to SFP slot 1 in the event of an error.
MADI SETUP & ROUTING
In this menu you set the parameters of the MADI protocol and
the latency compensation on the left screen and the routing
priority of the two SFP modules on the right screen.
Please note that the routing priority (MADI INPUT) only works
if both SFP modules are installed.
A32pro Dante set to both
In this preset, the two ports are separated from each other. However, the A32pro (Dante) accepts remote control commands from both ports.
A32pro Dante set to MIDI
In this preset, the two MIDI ports are connected and the A32pro (Dante) receives remote control commands from the physical MADI port.
A32pro Dante set to MIDI-over-MADI
In this preset, the two MIDI ports are connected and the A32pro (Dante) receives remote control commands from the MIDI-over-MADI port.
Please note that to use the MIDI-over-MADI control commands you still need a MADI device that supports MIDI-over-MADI.
MIDI ROUTING
In the MIDI menu, you can set the routing of the individual
MIDI ports (physical MIDI port (2x 1/8“ (3.5mm) jacks on the
back of the unit) as well as the MIDI stream from the MADI
signal (MIDI-over-MADI). The MIDI data is embedded in the
user bits of the MADI audio data stream.
There is a choice of three presets:
